First Human PatientFirst Human Patient
On Jan. 11, 1922, 14-year-old Leonard Thompson was the first human patient to receive insulin made by Banting and Best.
The initial test failed, causing only slight reductions in blood glucose levels.
A second series of "purified" insulin injections, produced by J.B. Collip, achieved the desired results.
Leonard's blood glucose dropped to normal, and he began to gain weight.
